Identifying Grammar Errors: Preposition Usage with 'Better'

This question asks to identify the grammatically incorrect part of the sentence: "She is better in mathematics than English." Let's analyze the sentence structure and word usage.

Sentence Breakdown and Analysis

  • "She is": This part of the sentence is grammatically correct. It correctly introduces the subject ("She") and the verb ("is").
  • "than English": This clause correctly follows the comparative adjective "better" and completes the comparison between mathematics and English. The conjunction "than" is appropriate for comparisons.
  • "better in mathematics": This is the part that requires closer examination. When comparing abilities or proficiency in a subject or skill, the standard preposition to use with the comparative adjective "better" (from "good") is "at", not "in". While "in" can sometimes be used, "at" is generally preferred and considered more grammatically precise in this context. For example, one would say "She is good at mathematics" and therefore, "She is better at mathematics than English."

Understanding Comparative Adjective Prepositions

The correct idiomatic expression for comparing proficiency in skills or subjects uses the preposition "at".

  • Correct Usage: "better at [subject/skill]"
  • Example: He is better at playing the piano than singing.
  • Example: Sarah is better at coding than graphic design.

The sentence uses "better in mathematics", which deviates from the standard and preferred grammatical structure for this type of comparison.

Conclusion on Sentence Parts

Based on standard English grammar rules regarding the use of prepositions with comparative adjectives like "better", the phrase "better in mathematics" contains the grammatical error.
